Abstract: ［Abstract］ Objective〖HTSS〗〓To study and to describe the mortality and incidence of bronchopulmonary dysplasia(BPD) of the very low birth weight infants (VLBWI) who required respiratory support.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Perinatal data and shortterm outcomes of 139 VLBWI were prospectively collected, all of whom were enrolled in the neonatal intensive care unit(NICU).
〖HTH〗〖WTHZ〗Results〖HTSS〗〓The overall incidence of BPD was 17.3%(24/139). The overall inhospital mortality was 32.4%(45/139). The composite incidence of BPD and/or death was 41.0%(57/139). The incidence of BPD in the surviving children was 25.5%. Thirtyseven patients in the dead children died after the family abandoned treatment. Low gestational age, respiratory distress syndrome(RDS), high Score for Neonatal Acute Physiology Perinatal ExtensionⅡ(SNAPPEⅡ) and intrauterine infection were the independent risk factors for BPD and/or death.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The mortality and/or incidence of BPD of the VLBWI who required respiratory support remained high in this hospital. The withdrawal of care was a major contributor to the high mortality. Low gestational age, RDS, high SNAPPEⅡ and intrauterine infection were the independent risk factors for BPD and/or death.
